[0002] At present, most of the existing laser scanning galvanometer systems (such as the prior art with the publication number of CN208255527U) are two-axis galvanometer systems, including an X-axis galvanometer assembly and a Y-axis galvanometer assembly. The X-axis galvanometer assembly and the Y-axis galvanometer assembly respectively have rotatable galvanometers, so as to emit the incident laser according to the set optical path. However, in the existing laser scanning galvanometer system, the X-axis galvanometer assembly and the Y-axis galvanometer assembly are installed on a bracket. When it needs to be applied to a cage optical system, a housing needs to be arranged outside the bracket. The housing is used to connect the cage rods. Due to the wrapping of the housing, it is difficult to install and disassemble the X-axis galvanometer assembly and the Y-axis galvanometer assembly inside the housing at this time, which needs to be improved. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0030] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication between two components or the interaction relationship between two components.

[0032] Reference Figures 1-5 Referring to

[0033] In this embodiment, the first driver 31 is arranged in the first clamping hole 211 along a first direction, and the first driver 31 drives the first galvanometer 32 to rotate around the first direction; the second driver 41 is arranged in the second clamping hole 221 along a second direction, and the second driver 41 drives the second galvanometer 42 to rotate around the second direction; wherein, the first direction and the second direction can be two perpendicular directions;

[0034] Regarding the clamping of the first driver 31 and the second driver 41 in the first clamping hole 211 and the second clamping hole 221, as Figure 4 shown, taking the structure of the second plate body 22 as an example, the second driver 41 is arranged in the second clamping hole 221, and a locking bolt (not shown) should be arranged in the second locking hole 223. Since the second locking hole 223 passes through the second elastic expansion and contraction joint 222, the second locking hole 223 is divided into two sections, namely the upper section (not marked in the figure) located above the second elastic expansion and contraction joint 222 and the lower section (not marked in the figure) located below the second elastic expansion and contraction joint 222. The upper section of the second locking hole 223 is a light hole, and the lower section of the second locking hole 223 is a threaded hole. Pass the locking bolt through the upper section of the second locking hole 223 and thread the locking bolt into the lower section of the second locking hole 223. When the locking bolt is tightened, the nut of the locking bolt abuts against the first plate body 21, and the second elastic expansion and contraction joint 222 is narrowed, so that the inner wall of the second clamping hole 221 forms an extrusion fit with the outside of the second driver 41, realizing the clamping and fixing of the second driver 41; when disassembling and assembling the second driver 41, a screwdriver or other screwing tool can be inserted into the cavity from the second adjustment hole 14 on the base body 1 and the locking bolt in the second locking hole 223 can be screwed; similarly, the clamping principle of the first driver 31 is the same as that of the second driver 41, so it will not be elaborated here.

[0035] In some embodiments, referring to Figure 5 , an assembly opening 17 is formed on the side of the base body 1, a cover plate is arranged on the assembly opening 17, and a first insertion hole for the X-axis galvanometer assembly 3 to pass through and a second insertion hole for the Y-axis galvanometer assembly 4 to pass through are formed on the cover plate.

[0036] In this embodiment, the assembly opening 17 can facilitate inserting the inner bracket 2 into the interior of the base body 1 (i.e., into the cavity). After the inner bracket 2 is fixed on the base body 1, the cover plate is then placed on the assembly opening 17 to reduce the risk of laser leakage. Subsequently, the X-axis galvanometer assembly 3 is inserted through the first jack and passed through to the first clamping hole 211; the Y-axis galvanometer assembly 4 is inserted through the second jack and passed through to the second clamping hole 221; finally, a screwing tool is used to clamp and fix the first driver 31 and the second driver 41.

[0037] In this embodiment, the bottom of the inner bracket 2 is fixedly connected to the base body 1 by bolts.

[0038] In some embodiments, both the first adjustment hole 13 and the second adjustment hole 14 are threaded holes. A first plugging member (not shown) is threadedly connected to the first adjustment hole 13, and a second plugging member (not shown) is threadedly connected to the second adjustment hole 14.

[0039] In this embodiment, when applying the two-axis galvanometer module of the present application, the first adjustment hole 13 and the second adjustment hole 14 can be blocked by the first plugging member and the second plugging member to reduce the risk of laser leakage; the first plugging member and the second plugging member are bolts, which are convenient to obtain materials.

[0040] In some embodiments, as Figure 5 shown, an observation hole 15 is provided at the top of the base body 1, and a third plugging member 16 is threadedly connected to the observation hole 15. Among them, when disassembling and assembling the first driver 31 and the second driver 41, the third plugging member 16 can be opened, and the internal situation of the base body 1 can be observed through the observation hole 15, so as to master the disassembly and assembly situation of the first driver 31 and the second driver 41.

[0041] It should be noted that when in use, the light inlet 11 and the light outlet 12 of the base body 1 are likely to be connected to other components, so it is difficult to observe the internal situation of the base body 1 from the light inlet 11 or the light outlet 12. The provision of the observation hole 15 can well solve the problem of being unable to observe the internal situation of the base body 1.

[0042] In some embodiments, as Figure 1 shown, a cage rod connection hole 18 is provided on the periphery of the light inlet 11. In this way, the base body 1 can be connected to the laser component on the cage optical system through the cage rod connection hole 18.

[0043] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
